Portable 2000 count digital multimeter
15
1.1.2 During use
∗ Never exceed the protection limit values indicated in the specifications
for each type of measurement.
∗ When the multimeter is linked to measurement circuits, do not
touch unused terminals.
∗ When the range of the value to be measured is unknown, check that
the range initially set on the multimeter is the highest possible or,
wherever possible, choose the autoranging mode.
∗ Before changing functions, disconnect the test leads from the circuit
under test.
∗ In TV repair work, or when carrying out measurements on power
switching circuits, remember that high amplitude voltage pulses at the
test points can damage the multimeter.
Use of a TV filter will attenuate any such pulses.
∗ Never perform resistance or continuty measurements on live circuits.

1.1.4 Instructions
∗ Before opening up the instrument, always disconnect from all sources
of electric current and make sure you are not charged with static
electricity, which may destroy internal components.
∗ Any adjustment, maintenance or repair work carried out on the
multimeter while it is live should be carried out only by appropriately
qualified personnel, after having taken into account the instructions in
this present manual.
∗ A "qualified person" is someone who is familiar with the installation,
construction and operation of the equipment and the hazards
involved. He is trained and authorized to energize and de-energize
circuits and equipment in accordance with established practices.
∗ When the instrument is opened up, remember that some internal
capacitors can retain a dangerous potential even after the instrument
is switched off.
